Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDRs are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts .
These electronic contro l modules also record
vehicle-related data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
p ing and improves driving stability. ESC de­
tects cr itical s ituations such as the vehicle oversteering and
understeering or the wheels
spinning . The vehicle is stabilized by applying
the brakes or reducing engine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL) and
hill descent control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking. The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­ al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
sta rt, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels .
This function is available up to about 60 mph
(100 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomat ically when conditions have returned to
normal.

228 Intellig ent technol ogy
- Never let the vehicle ro ll to a stop with
the engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Servotronic - advanced
power steering system
The power steering systems uses the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys­
tem senses the road speed and electronically
adjusts powe r assistance to provide comforta­
b le and safe steering response exact ly match­
ed to the vehicle speed.
Power steering w ill not work if the eng ine is
off. As a result, the steering wheel w ill be hard
to turn.
The power steering fluid level is checked dur­
ing the scheduled ma intenance serv ices .
@ Note
If the re is an electronic malfunct ion, ser­
votronic
w ill still function like a conven­
tional power steer ing system, p roviding a
constant steer ing support force that is no
longer proportionate to the vehicle speed .
This is most noticeab le when turning the
steering whee l at low speeds (for examp le
when parking), -more effort will be re­
quired than usual.
- Be aware of the different than usua l
steering response and adjust your steer­ i ng force accord ingly.
- Have the prob lem checked and set right
by an Aud i dealer as soon as possible.
- When the engine is running , never hold
the steering whee l turned all the way to
the right or to the left for longer than
15
seconds . The power steer ing pump w ill
overheat the hydraulic flu id if you keep holding the steering wheel turned all the
way . This is likely to damage the power
steering system.
- If the powe r stee ring system sho uld fail
entirely, or if the engine is not running
(for example, whi le be ing towed), you
will still be able to steer the ve hicle.
However,
considerably more effort will
be required to do so .
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately .
- The power steering system requ ires a
specially formulated hyd ra ulic fluid . The
powe r stee ring reservoir is the one locat­
ed farthest to the rear on the left s ide of
the engine comp artment r=;,
page 259.
T he correct fluid level in the reservoir is
important for proper functioning of the
power steering .
Driving with your
quattro
With all-wheel drive , all four wheels are driv­
en .
Gen eral information
With all-wheel drive, power is distributed to
all four wheels. This happens au toma tically
depending on your driving style and the road
condit ions at the time . See also r=;,
page 224 .
Winter tire s
When driving in the winter, yo ur vehicle with
a ll-wheel drive has an advantage, even wi th
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all -sea ­
son tires) for improved dr iveability and brak­
ing : these tires must be mounted o n
all four
wheels. See also r=;, page 288, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also appl ies to veh icles
with all-wheel driver=;,
page 289, Snow
chains .

274 T ire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
(D Note
Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in ­
dicate a low sidewall for improved steering re­
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica l in those seasons . Audi recommends
using winter tires during the winter
months . Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicl e w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi ­
tioning and additional weight of optiona l
equipment.
Extra load tire
me ans a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of
t h e ve hicl e. .,.
